IMPROVEMENT IN SOFA-BEDSTEADS.

Specification forming part of Letters Patent No. 170,258, dated November23, 1875; application filed May 5, 1875.

To all whom it may concern:

Be it known that I, WILLIAM R. HAMIL- TON, of Pittsburg, county ofAllegheny, State of Pennsylvania, have invented or discovered a new anduseful Improvement in Folding Bed Lounge or Sofa; and I do herebydeclare the following to be a full, clear, concise, and exactdescription thereof, reference being had to the accompanying drawing,making a part of this specification, in which-like letters indicatinglike parts Figure 1 is a perspective view in outline of theframe-work ofmy improved folding lounge or sofa in an unfolded position. Fig. 2 isv alike view. of the stationary .half of the frame, with the hinge thatconnects the other or folding half. Fig. 3 is a reduced cross-section ofthe same with the two halves folded together; and Fig. 4 is a likesection, illustrating the motion of the movable half in unfolding.

The main frame of the stationary part of the lounge or sofa is made withside rails a, footrail a and raised head piece 04. the side railssloping, in a lounge-frame, up at the head end in the usual way, andwith or without the raised back a The folding part has like side railsb,foot-rail b the head end of the side rails rising to the head-rail W.Front and foot faceboards dd are added for the usual purposes; and, forbetter protection against dust, vermin, &c., a close unjointed woodenbottom, 0, is made to each half, on which and the side and end rails theupholstering is built up. The two halves are connected together by abent hinge, s, the two ends of which are the folding half maybe carriedup and overin the arc of a circle without being inverted, as illustratedin Fig. 4, to the other position. But, to make better provision forupholstering, I raise the foot and head rails 01. a

whereby, when the folding half is laid over onto the other, a space, '0,of about one inch as shown in Fig. 1, will let the top of the foldingframe come below the top of the stationary frame, whereby I make roomfor a like amount of upholstering as a bed, and also a finished cushionon top of that, which adapts it for sitting purposes.

For convenience in cleaning, repairing, 850., I make the two partsseparable, which I do by the use of a hook-hinge, as shown, but with aremovable stop, t, inserted at the base of such hook, to keep it fromoomingout when not desired, and with a like stop'at the base of one ofthe books at the other end of the hinge.

I claim as my invention 1. The herein-described two halves of a foldingsofa, connected together by a bent hookhinge constructed as described,and rendered separable from each other by means of the adjust-ableconnection of said hinge with one of the said halves, substantially asshown, and for the purpose set forth.

2. In combination with the herein-described two halves of a foldingsofa-bed, the connecting-hinge, constructed with bent arms 8 and gether,for the purpose of holding bedding,

850., substantially as shown and described.

In testimony whereof I havehereunto set my hand.
